Mr. Frazer has reported the existence of a plant he referred to Banksia grandis, with a trunk fifty feet high, and frequently more than two feet and a half in diameter, occupying the barren hills on the banks of the river, at Point Frazer; but as I have seen no specimens of the plant, I do not know whether he determined the species rightly or not. It is however certain that B. Menziesii, a very noble species, is found here, together with B. prionotes,160 allied to B. æmula, and B. Aquifolium,161 a new instance of the Isostylis division, with very much the look of a Dryandra.
Of Isopogon and Petrophila, two genera perhaps better united, there are many interesting species, especially I. sphærocephalus,163 so like P. linearis that the one may be mistaken for the other; P. seminuda,166 a fine plant with
